ETC Successfully Completes Factory Acceptance Testing of Night Vision Training System for Royal Saudi Air Force

SOUTHAMPTON, Pa., June 6, 2011 — Environmental Tectonics Corporation (ETCC: PK) (“ETC” or the “Company”) (http://www.etcusa.com/) today announced the completion of Factory Acceptance of a Night Vision Training System (NVTS), sold to the Royal Saudi Air Force (RSAF) through ETC’s Aircrew Training Systems (ATS) business unit. The new NVTS will be shipped to Saudi Arabia to be installed in the new RSAF aeromedical training center.

The NVTS consists of a computer-based training system with automated training programs for unaided vision and Night Vision Goggle (NVG) flying in the night environment and a Terrain Model Board designed to replicate the Saudi Arabia terrain. The NVTS will be installed in a theater-style classroom specifically designed for night vision training in the purpose-built RSAF areomedical training center.

The RSAF will use ETC’s NVTS to train their pilots how to safely and effectively conduct unaided vision night flying operations as well as the safe use of their own NVGs (NVGs are not provided with ETC’s NVTS). This type of training complements the RSAF human factors training program by training their pilots in the procedures and techniques for coping with the hazards associated with night flying. The RSAF is committed to the professional development and safety of their pilots through modernization of its aviation physiology training program.

ETC is proud to be the supplier of state-of-the-art aviation physiology training equipment to the RSAF. More detailed specifications for the NVTS and other Aircrew Training Systems is available by contacting: Robin Valinski, rvalinski@etcusa.com, Sales and Marketing Coordinator, ATS at ETC, 125 James Way, Southampton, PA 18966, USA.
